non-specifc ischemic (ISC_)
Non-specific ischemic (ISC_) is a type of electrocardiogram (ECG) finding that indicates a possible lack of blood flow and oxygen to the heart muscle, but without any clear evidence of a specific location or artery being affected.
ISC_ can be asymptomatic, meaning that the individual may not experience any noticeable symptoms. However, some individuals may experience symptoms such as chest pain, shortness of breath, palpitations, and dizziness.
When reviewing an ECG for ISC_, it is important to pay attention to the presence of ST-T wave changes that are not localized to a specific area or lead. Other things to pay attention to include the presence of T wave inversions, ST segment depression or elevation, and the morphology of the QRS complexes.
- Look for non-specific ST-T wave changes
- Check for the presence of T wave inversions
- Observe the presence of ST segment depression or elevation
- Examine the morphology of the QRS complexes
If ISC_ is suspected, further testing such as stress testing, echocardiography, or cardiac catheterization may be recommended to determine if there is an underlying cardiovascular condition that requires treatment.
